I read that the maximun size of Dataverse is 4TB in this documentation (https://docs.microsoft.com/en-us/powerapps/teams/data-platform-compare):

However, other documentation (https://docs.microsoft.com/en-us/power-platform/admin/environments-overview) have notes that the defaut environment is limited to 32GB and the free storage is 3GB Dataverse Database Capacity, 3GB Dataverse File Capacity, and 1GB Dataverse Log Capacity.

Our school is using Office 365 Education License and we used Dataverse to store the data, we only have 01 default environment within the tenant.
I'm pretty confused and would like to ask if we continue to store our data in Dataverse, what is the maximum capacity of Dataverse which we could use? Will the maximum capacity be 4TB, 32GB or 3GB? What will happen if our data size beyond this capacity?
If we create more production environments in our tenant, what is the capacity of these environments?
This information is pretty important because to we created our databases in Dataverse.
Thanks,
